It wouldn’t be a true throwback race at Darlington Raceway without the No. 43 on the track. But with STP returning for the Labor Day weekend race, the 43 machine is really getting back to its roots when Aric Almirola starts the Southern 500.

The retro scheme for Almirola’s ride is a throwback to the 1972 paint scheme when STP first came aboard. Richard Petty won his fourth championship that season and would go on to win three more with STP on the hood.

“It will be neat to see the car that started our partnership with STP 43 years ago back on track at Darlington,” Petty said in a release. “It will be fun to see all the throwback schemes racing at Darlington and on Labor Day Weekend. It just feels right to have the Southern 500 back to Labor Day Weekend and is fitting that we celebrate tradition there with throwback paint schemes.”

Almirola has never finished inside the top 10 at Darlington, so the odds of another win with the STP across the hood seems unlikely. But with plenty of tradition and a slick ride, Almirola and the No. 43 will certainly stick out in a field of throwbacks during the Southern 500.
